Back in the days when we were using IBM 286XT & AT computers, the Canadian  
R-2000 energy-efficient housing program had at its core, the HOTCAN  
thermal modeling & performance analysis program.

Back then Windoze did not yet exist so the HOTCAN program interface was  
blinking text on a black & white display.

The program would prompt the user for inputs consisting of details about  
the proposed building and then when one had completed entering all of the  
inputs, the program would provide a print-out of the proposed building's  
energy consumption and how it compared to the R-2000 performance standard  
for a building of the same size in the same location.

The program output would provide info on payback periods so that one could  
(as per Sacie's wish) see the cost benefits (or liabilities) that making  
specific changes to the design would provide.

That HOTCAN program and its successors through the various iterations of  
the Windoze era HOT2000 have been invaluable design tools in use by  
Canadian designers for over 30 years and I'm pretty sure that's been  
available as a free download for at least 15 or 20 of those years.

Presumably Murricans and Euro-peein's have had/utilised similar resources ?
